freecad layers

Compile FreeCAD on Windows[Email protected]1.IntroductionFreecad is a parametric three-dimensional modeling software, mainly used for arbitrary size of the actual model design. Parametric modeling allows you to easily modify your design by modifying the relevant parameters. FREECAD is open source software and provides a convenient way to customize and also provides scripts to expand functionality to suit yo

Freecad is an open-source CAD software. Although its functions are not perfect yet, it demonstrates how to build a complete CAD System-cross-platform. I have also studied how to build a CAD System in Windows to imitate the software that I am working on, but it involves MFC, VBA, and COM. Although I have always felt that the behaviors that use Microsoft's technologies and advocate Mac and Linux are very emotional, I would rather cool: I cannot cross-

dreamweaver| Tutorials | Getting Started A layer (Layer) is an HTML page element that you can position anywhere on the page. Layers can contain text, images, or other HTML documents. The appearance of the layer makes the Web page extend from two-dimensional plane to three dimensions. You can make elements on the page overlap and complex layouts. First, take a look at the following figure: Let's start with a layer. 1, in the "Window" menu, select "Lay

theoryFirst, I would like to ask a few questions first:(1) In Webgis, is the topographic map itself raster or vector data?(2) When the user needs to interact with the layer, such as the need for the layer to respond to the Click event, return the attribute at the click, when the layer is displayed with the data of the grid, or vector data?(3) It is necessary to determine the topological relationship of two layers, such as determining which houses in

A lot of beginners do not know much about PS, there is a layer problem and do not understand how to solve, I now share with you about the layer of solutions. Method/Step 1, the layer will suddenly disappear, do not know where to find? In fact, the window in the menu bar- layer can be found, you can also find F7 through the shortcut keys. 2, how to link layers and unlock the connection layer, the connection layer is mainly us

If you observe"FractalProperties"Window"Layers"Panel, you will see two layers and Their thumbnail list.But when you watch yourFragmentYou can only see the display of the grayscale style layer.This is because the top layer is displayed in "normal" mode of 100%, which means that you can see any layer below it now.To check whether other layers are still in use, clic

Here is the vector layer loading method, because the layer itself is already produced by the Mxd class project file, so directly using the Mxd loading modeIf(Axmapcontrol1.checkmxfile (Shpfile))//determine if an mxd file{IArray pArry; PArry=axmapcontrol1.readmxmaps (Shpfile, Type.Missing); IMap PMap; for(inti =0; i ) {PMap= Parry.get_element (i) asIMap; if(Pmap.name = ="Layers") {Axmapcontrol1.mousepointer=Esricontrolsmousepointer.esri

IP, can not contact with the outside world. Solution 1: If you can buy so many extranet IP addresses to use and then load balance to the real Web server when TCP links are built, let the client and server establish a TCP link Solution 2: Quote: All problems with computers can be solved by creating a layer of virtual layers. You can virtualize all server host IP to a load-balanced server IP, so that all hosts of the server cluster can access the ext

Errors that may occur after you start editing:If ArcMap encounters a problem starting an edit session on the selected data, a dialog box pops up to provide additional information. You may receive an error, warning, or informational message. When an error occurs, the user cannot start any edit sessions. You can edit the data only if the problem is resolved. You receive an error message if there are no editable data sources, licensing issues (for example, if you try to edit certain types

describe the position of the layer on the z-axis.Practical Application of Zposition:In addition to moving and rotating layers in three-dimensional space, the most useful feature is to change the order in which layers are displayed.Self.greenView.layer.zPosition = 1.0f;You can use this setting to make the view appear before the view that is smaller than its zposition.In fact, there is no need to add too muc

The biggest problem with traditional layering is that it splits the relationship between the upper and lower layers, turns the relationship between them into simple interface calls, and turns it into full interface formalism. At the same time, it is ignored that the lower layer provides services for the upper layer, rather than independently. The services provided by the lower layer should be governed by the upper layer. Of course

For example, how can the form data in C be passed to the M layer after the validation is done? The current use is to assemble the data into the corresponding domain object in action, and then pass the parameter to the model~ However, by doing so, the complex assembly process is undoubtedly given to the action developer, which makes the division of responsibilities between the scoring layers unreasonable, and the C and M

When I first started contacting layer three, I only made two examples of login widgets. Drawing a simple package diagram, it can be said that the reconstruction of the back room left a lot of work (because the three-layer understanding of no depth, also did not understand their own things). However, the total owed is still. When the machine room is reconstructed, the problem arises. If only use three layer + entity, I can make, but, require refactoring can not only use three layer + entity, then

Multiple layers of jquery's anonymous method and multiple layers of jquery's anonymous method Anonymous method: (Function (x) {}) (3 ); Explanation: the first () is a method, and the second () is a parameter in the method. Purpose: The anonymous method is automatically executed in javascript. For example, the start method of jquery can be written as an anonymous method: (Function ($) {}) (jQuery); // T
